Tomer’s Take: A shifting Western pattern delivers 3-6 inches of new snow to the Tetons today (12/10), generates 30-70mph wind gusts across CO’s Continental Divide and light snow, and eventually might force the development of a storm system in Southern CO/Northern NM by 12/13-12/14. Pattern remains mostly dry for CA through 12/18, and minimal snow […]

Tomer’s Take: Two shots of accumulating snow hit WY on 12/10 and 12/11. 30-60mph wind gusts hit Colorado’s Continental Divide on 12/10. Shifting flow pattern favors ID, WY, MT, PNW, BC through 12/18. Unfortunately, UT and CA look mostly dry through 12/18. My forecast video: Windy CO Continental Divide 12/10 Valid 7am 12/10. Expect 30-60mph […]

Tomer’s Take: Snow continues today in WY, UT, and CO. Saturday is dry. Additional snow hits the Tetons and Colorado on Sunday and Monday. In the Northeast, a windy storm system hits 12/10-12/11 with rain initially then changing over to snow on 12/11. About 7 inches in 24 hours at Winter Park, CO with a […]

Tomer’s Take: The next storm system departs the PNW and hits ID, MT, WY, UT, and CO 12/7-12/9. This same storm system develops into a strong, windy East Coast storm system with rain on 12/10 and then snow 12/11. 7″ in 24 hours at Big Sky and snow continues to fall plus 30-50mph wind gusts. […]

Tomer’s Take: Moderate to heavy snow accumulation hits ID, MT, WY, UT, and CO 12/7-12/8 with light accumulation 12/10. Out East, a large, windy storm system pushes most ski areas into the warm sector with primarily rain on PM 12/10 changing to snow on 12/11. My PM forecast video: Current Setup Water vapor satellite shows […]

Tomer’s Take: Atmospheric river continues in the PNW next 24 hours with high rain/snow levels. This storm system then breaks loose and races through the Intermountain West 12/7-12/8. A second minor, fast-moving storm system rides its coattails 12/9-12/10. A third feature is possible 12/12-12/13; A cold front dives south through CO and NM and might […]

Tomer’s Take: The powerful WNW Flow delivered 40-50 inch grand totals to parts of UT and CO. The next storm system is already hitting the PNW/BC with heavy precipitation. It’s part of a strong intensity atmospheric river. This storm system and one behind it move through ID, MT, WY, UT and CO 12/7-12/11. Grand Totals: […]

Tomer’s Take: WNW Flow continues to deliver snow in UT and CO through early 12/4 then drier. Light to moderate additional accumulation in ID, MT, WY. Brutally cold and windy above treeline in Colorado with 30-70mph gusts and single digit air temps. Then next storm system hits the Intermountain West 12/7-12/9. A strong intensity atmospheric […]

*230pm 12/2 Update: Lull period for CO & UT then next big push of moisture/snow arrives tonight through 12/3. Tomer’s Take: Snow continues in waves across the PNW, BC, ID, WY, UT, CO. The next big moisture push for UT and the C+N Colorado mountain zones arrives Saturday afternoon (12/2) through Sunday (12/3). Looking down […]

*2:30pm 12/1 Update: Bulk of accumulation in Colorado and Utah arrives Saturday evening (12/2) through Sunday (12/3). Tomer’s Take: The ‘golden combo’ of a moderate to strong intensity atmospheric river, stacked WNW Flow, and high ratios is underway in PNW, BC, ID, WY, UT, and C+N Colorado mountain zones. It’s a three day event, 12/1-12/3, […]
